Question

If two dice are rolled, what is the probability that their sum will be a number greater than 5?

[A] 1/6
[B] 1/3
[C] 13/18
[D] 5/6
[E] None of these

I think it's [C], but that's just a wild guess.

Answer 1

Rolls >5.
2,4
4,2
2,5

3,3
3,4
4,3

6,6

Are all the possibilities included?

22/36 = ?

Answer 2

@PsyDAG

Um.....
You forgot just two, but's that okay:
1+6=6
6+1=6

22/36, reduced down equals 11/18.
But with the two that you missed, it equals 13/18.

Answer 3

@PsyDAG
At least I think..... it euqals 13/18
x(
Gah! This math stuff

Answer 4

Sorry that I omitted 2. However, that would bring it to 24/36 = 12/18 = 2/3. If we omitted another two, it would be 26/36 = 13/18.

Answer 5

Sorry that I omitted 2. However, that would bring it to 24/36 = 12/18 = 2/3. If we omitted another two, like 1,5 and 5,1, it would be 26/36 = 13/18.
